Breast cancer can be a devastating illness. Breastcancer.org writes that approximately 1 in 8 U.S. women will develop invasive breast cancer over the course of her lifetime. A man’s lifetime risk of getting breast cancer is about 1 in 1,000. The American Cancer Society reported on Oct. 4, 2013, "Study Links Walking to Lower Breast Cancer Risk."
Walking at least 7 hours a week is associated with a 14 percent lower risk of developing breast cancer after menopause, according to researchers from the American Cancer Society. This finding supports many other studies which have shown regular exercise can help women lower their risk of breast cancer. This study found exercise helped women whether or not they were overweight, and helped them even if they gained weight during the course of the study.
The women with a 14% lower risk of breast cancer walked at a moderate pace of about 3 miles per hour. Those women who walked and did more vigorous exercise had a 25% lower risk of breast cancer compared to the least active women. Clearly, exercise in the form of walking, which is also good for weight control, cardiovascular health, and mental health, is a great way to promote better health in many ways.
